Recycle rate of automobile is 80%, and remaining 20% is disposed by landfill. Most items of remaining 20% are occupied with ASR, but since the landfill disposal place is insufficient, necessity of raising recycling rate is increasing. In order to solve this problem, field test of ASR recycle plant has been operated for two years or more. The feature of this system is combination of gasification by pyrolysis of ASR and reforming of pyrolysis gas. This system enables the conversion of ASR into fuel gas. Fuel gas that consists of hydrogen and carbon monoxide as the main inflammable components can be used as fuel for gas engine generators and heat source of pyrolysis kiln. This paper introduces gas engine operation characteristics, such as power efficiency and operation stability.
